NuttX 7.28 seemed to handle this gracefully, but officially passing NULL
results in undefined behavior, and with 7.29 leads to a hardfault.
This happens on configs with flash-based params, on the first unsuccessful
import attempt.
Reduces clutter in the boot output (now that we have it in the log).
On omnibus for example we see:
ERROR [param] Parameter SENS_EN_BATT not found
ERROR [param] Parameter SENS_EN_LL40LS not found
ERROR [param] Parameter SENS_EN_LL40LS not found
ERROR [param] Parameter SENS_EN_MB12XX not found
ERROR [param] Parameter SENS_EN_PGA460 not found
ERROR [param] Parameter SENS_EN_SF1XX not found
ERROR [param] Parameter SENS_EN_TRANGER not found
- the flash-backend is selected by specifying nullptr as file or -1 as fd
- the default file is nullptr, and thus the FLASH
- 'param select' has no effect, FLASH is always the default
Thus there should be no functional change to existing setups.
